Sounds like a challenge

Wimpy Boardwalk is our 28th Island on Poptropica, and that means the challenge is on to earn all 28 Medallions. Not many Poptropicans have been able to pull it off so far, but those who have are able to show it off on their profile page.

so? they want us to finish all the islands but they keep publishing new islands which makes it hard for people with new accounts or anyone who has not finished all the islands. like on my new account i have finished some islands (now i’m trying to finish R.T.V. island. the annoying people keep voting me off 😦 )
